Answer:

15 units per unit

Step-by-step explanation:

From the graph we can easily tell that y increases from 0 to 15 as x increases from 2 to 3.

Thus, the average rate of change of f(x) on the interval [2, 3] is:

1 15 - 0 15 units

--------- * ----------- = -------------- = 15 units (rise) per unit (run).

3 - 2 1 1

In triangle ABC, c is the hypotenuse, 0=25°, and b =3, Find the length of c ?

Charra [1.4K]

Answer:

$\large\boxed{c\approx3.31}$

Step-by-step explanation:

Use cosine:

$cosine=\dfrac{adjacent}{hypotenuse}$

$\cos\theta=\dfrac{b}{c}$

We have:

$\theta=25^o\to\cos25^o\approx0.9063\\\\b=3$

Substitute:

$\dfrac{3}{c}=0.9063$

$\dfrac{3}{c}=\dfrac{9063}{10000}$ <em>cross multiply</em>

$9063c=30000$ <em>divide both sides by 9063</em>

$c\approx3.31$

The function f is defined by f(x) = x^2 + 2

jok3333 [9.3K]

It's simple,

f(x)=x^2+2
is the formula that you start with

you are then given f(x). f(4x)

you then plug in 4x

4x=(4x)^2+2

you then solve for x

4x=16x+2
-16x. -16x

-12x=2
÷-12. ÷-12

x=0.16 is your answer

Please help... How many odd perfect squares are between 5 and 211?

frez [133]

Answer:

we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

Step-by-step explanation:

Let us check by taking squares

3² = 9

5² = 25

7² = 49

9² = 81

11² = 121

13² = 169

As taking 14² = 256 would exceed 211, and 1² = 1 is smaller than 5.

Therefore, we conclude that the total number of perfect odd squares between 5 and 211 will be: 6
